An object of this invention is the provision of simple means for holding screen frames. storm sashes or the like removably locked on a window casing.

A further object is to secure on the vertical stiles of a window screen or the like, a jointed spring member designed to engage with an offset lug on the stop bead of a window casing and to be locked in such engagement, and in which the said locking means is readily releasable so that the screen may be easily removed from the casing when occasion requires as well as being firmly sustained in the casing without liability of rattlingor accidental removal.

To the attainment of the above broadly stated objects and others which will appear as the nature of the invention is better understood, the improvement further resides in certain novel features of construction, combination and operative association of parts, a satisfactory embodiment of which is illustrated by the accompanying drawings.

In the drawings:

Figure 1 is a: fragmentary perspective view of a screen sustained in a window casing in accordance with this invention, parts being in section.

Figure 2 is a fragmentary perspective view showing the holding means released.

Figure 3 is an enlarged elevation; showing the parts as arranged in Figure 1.

In the drawings a window casing is broadly indicated by the numeral 1 and the outer stop bead therefor, by the numeral 2. Resting on the sill of the casing, contacting with the lower and outer face of the said casing and with the stop bead 2 there is the frame 3 for a screen, storm sash or the like.

Secured on the vertical stiles of the frame 3, by means 4, there are plates 5, only one being shown in the drawings. The plates are of metal and embody a natural resiliency. The plate 5 has its ends rounded upon it self to provide eyes 6 and 7, respectively, and passing through each of these eyes there is a ail member 8 and 9, respectively. Hingedly secured to the lower bail member 9 there is one end of a second spring plate 10. The outer or free end of this plate is rounded inwardly and from thence outwardly, as at 11, and over this end there is designed to be swung the bail 8.

Secured by means 12 on the outer face of the stop bead 2 there is the inner plate 13 of an angle bracket. The angle flange of the bracket is centrally bulged inwardly upon itself, as at 14, and against this bulged portion the spring plate 10 is designed to contact when the frame 3 is held on the casing. By simply swinging the bail 8 out of engagement with the inwardly rounded portion 11 of the plate 10, the latter will swing on the lower bail 9 to the position illustrated in Figure 2 of the drawings so that the frame may be thus readily removed from the window casing.

The simplicity of my construction, the cheapness at which it maybe manufactured and the ease in which it may be applied to or removed from a window casing and a frame, and locked or released, will, it is thought, be perfectly apparent to those skilled in the art to which this invention relates when the foregoing description has been carefully read in connection with the accompanying drawlngs.

Having described the invention, I claim 1. The combination with a window casing and a frame that is designed to be removably sustained on the casing, said means comprising a plate fixed on the inner stile of the frame, a second plate hingedly secured to the first mentioned plate, an angle bracket fixed on the side of the casing against which the last mentioned plate is designed to be swung and to contact therewith, and means for latching the free end of the last mentioned plate to the first mentioned plate.

2. The combination with a window casing and a frame which is removably arranged thereon, of means for locking the frame in the casing, comprising a spring plate fixed at points away from its ends toa stile of the frame and having its ends rounded to provide eyes, a bail swingable in each eye, a second spring plate having one of its ends hingedly secured to one of said bails, and designed to have its opposite end engaged by the second bail on the first mentioned plate and an angle bracket fixed on the window casing and designed for contacting engagement by the last mentioned plate.

3. The combination with a window casing and a frame which is removably arranged thereon, of means for looking the frame in the casing, comprising a spring, plate fixed at points away from its ends to a stile of the frame and having its ends rounded to provide eyes, a bail swingably supported in each eye, a second spring plate having one of its ends hingedly secured to one of said bails, and having its free end rounded inwardly and outwardly for the reception of the second bail on the first mentioned plate when the said bail is swung over the said end of the second spring plate, an angle bracket fixed inwardly for engagement with the last men- 10 tioned plate. I

In testimony whereof I afliX my signature.
